Im not sure how often they say duck the people down south but its definitely part of the derbyshire dialect which i guess must have spread (had to look it up to make sure it wasnt just what locals have told me!), though i never heard it until i came south to sheffield.

As for love i have heard old women say it etc but its not used in quite the same way as it is in sheffield, which is by literally everyone! Again its just a part of sheffield's own dialect.

Both not a patch on cumbrian obviously, which has different dialects depending on which valley you are in! as in 6 to me is sethera but only a few miles away 6 is teezie! Anyone say inbred? haha (its ok im one of them!)
